“A man came to the Prophet (ṣ) and said, ‘O Messenger of Allah, there is no ugly action but that I have performed it; is there any possibility of repentance for me?’ The Messenger of Allah (ṣ) replied, ‘Are any of your parents alive?’ He said, ‘My father.’ He (ṣ) said, ‘Then go and be kind to him.’ So when he had left, the Messenger of Allah (ṣ) commented, ‘If only it was his mother [who was alive]!’”
